Across
  1. 4. the number of complete waves that pass a particular point in a unit of time
  2. 7. a wave in which the medium's particles move in a direction that is perpendicular to the direction of the wave's movement
  3. 9. the effect produced by the combination of two or more waves
  4. 10. section in a longitudinal wave where the particles are tightly packed together
  5. 12. the maximum distance a wave vibrates from its rest position
  6. 14. the time it takes two successive wave crests or troughs to pass a given point
  7. 16. the bending of a wave because of a change in the wave's speed as it passes from one medium to another
  8. 18. the highest point of a transverse wave
  9. 19. the distance between a trough and a crest
  10. 21. the distance between corresponding points on a wave
Down
  1. 1. the conversion of a wave's energy into another form of energy
  2. 2. the point where destructive interference causes no displacement
  3. 3. the place where constructive interference causes the largest wave
  4. 5. a disturbance that transfers energy through matter or space
  5. 6. a wave in which the medium's particles move in a circular motion
  6. 8. a section in a longitudinal wave where the particles are loosely packed together
  7. 11. the bending of a wave around a barrier
  8. 13. a wave in which the movement of the medium's particles is parallel to the direction of the wave's movement
  9. 15. the bouncing back of a wave after it hits a barrier that does not absorb all of its energy
  10. 17. any substance through which a wave can travel
  11. 20. the lowest point of a transverse wave
